Pricing on the online booking systems is a difficult task for the host, the systems usually set the prices that are lower than the general premises and quality, and that only gives benefits to the system by easily attracting the customer to use the service. The setting price of the new accommodation is often based on location, the number of beds, type of house and so on. The main problem is to predict the most reasonable price for the host. This paper aims to study the use of machine learning and sentiment analysis for predicting the price of online booking systems.

In particular, an empirical study is performed first for some well-known classification models for the problems. The authors then propose to apply k-means, a clustering technique, together with Gradient Boost and XGBoost models to improve the prediction performance. Experiments are conducted and tested for real Airbnb data sets collected in London City.

Experimental results are given and compared to show that the authors’ method outperforms to an updated method.

The authors use k-means and sampling together with Gradient Boost and XGBoost models to improve the prediction performance.

The purpose of this study is to show the presence of market discipline and provide an explanation for bank risk nondisclosure behavior, specifically market risk (MR), credit risk (CR), operational risk (OR) and counterparty credit risk (CCR). The response of market discipline when banks comply with Basel III capital and liquidity restrictions is also investigated in this study.

The study used the Lasso regression method to give accurate results with the lowest error when using small observational data with a large number of features.

First, theoretically, the study points to the presence of market discipline and its sensitivity to the risks disclosed by the bank, especially when applying capital regulations under Basel III. In addition, the study also shows differences between the developed and emerging countries in the sensitivity of market discipline to factors when considering banking regulations. Finally, an interesting result that the study shows is that the higher the index of economic freedom, the weaker the market discipline is, especially for emerging countries.

The study’s findings have several important implications: (1) help regulators devise policies to manage banks' risk and meet liquidity and capital requirements according to the Basel III framework. The effectiveness of market discipline is reduced, and banking regulators need to compensate by strengthening their supervisory functions. (2) Showed the reasons why banks ignore the disclosure of bank risks according to the provisions of the third pillar of the Basel III framework. Because when following the Basel III framework, depositors demand higher interest rates or increase market discipline towards riskier banks.

This study is the first attempt to assess market discipline under the new capital and liquidity regulations using the Lasso regression model as suggested by Tibshirani (1996, 2011), Hastie et al. (2009, 2015). This is also the first study to look at the impact of four different forms of risk on market discipline (as required by the Basel regulatory framework to improve disclosure).

This paper presents the outcomes of the international project “Protecting Landscape Heritage: a requalification project as an instrument for the re-birth of Quang Tri Old Citadel in Vietnam”, achieved with scientific cooperation between the Università Politecnica delle Marche (Italy) and Hue University of Sciences (Vietnam) funded by the Italian Ministry of Foreign Affairs and International Cooperation and Ministry of Science and Technology of Vietnam. The research focuses on the Quang Tri Citadel, founded in 1809 and now in an advanced state of degradation.

For the purpose of rehabilitation, the wide multidisciplinary project first examined the historical context of the military model, the architectural aspects of the structure, the characterization of the existing materials, the degradation levels of different parts, and, finally, a proposal of the suggested interventions.

The original structure and geometry were extrapolated and studied. Building materials were produced with nearby raw materials. Firing temperatures of bricks ranged from 800 to 1,000 °C, hydraulic lime was supposed the binder of the mortar with a calcination temperature lower than 1,000 °C. Damage assessment was provided and after these analyses a requalification project was proposed so the cultural heritage can play a role for the future in the dialog between different cultures.

The requalification project achieved by an integrated analytical approach defines aspects in relation to the restoration of the structures, enabling compliance with the geometry, techniques, building materials used in the original construction and allowing its guardianship and management to align with the historical context of the architectural heritage.

The authors estimated the hidden overhead (capital diversion or wasteful use of capital) of Vietnam state-owned enterprises (SOEs).

The authors used a panel data set of 10,200 Vietnam SOEs observed over the period 2010–2018. The authors modeled and estimated the hidden overhead by using a stochastic production frontier. The hidden overhead parameter is modelled as the technical inefficiency in the production function.

Vietnam SOEs are very capital intensive. The hidden overhead (or the wasteful use of capital) is very high with an average rate of 69%.

Alternative estimation methods should be used to account for endogeneity in production inputs. Lack of comparison with the Vietnam private firms.

The paper proposes an original way to quantify hidden overhead (or capital diversion) in the Vietnam SOEs. The finding (a capital diversion rate of 69% on average) is astonishing. It calls for an urgent and profound reform of the Vietnam SOEs.

Understanding customers’ expertise for better service co-creation is of great importance. To be an effective co-creator, customers need to have much more knowledge than a basic literacy, which is appropriate for passive service consumption. This paper aims to propose the concept of customer service co-creation literacy (SCL) to capture not only the basic expertise but also the expertise for active service co-creation. This study then investigates how SCL can be cultivated and how it facilitates customer co-creation behavior, which subsequently leads to enhanced value.

A conceptual model was developed and tested in the health-care service context using a sample of 310 patients. CB-SEM/AMOS software package was used for data analysis.

SCL has different impacts on three components of co-creation behavior, which in turn influence the service value differently. SCL not only solely facilitates co-creation behavior but also directly increases customer value. SCL can be cultivated by social support and frontline employee interaction.

The findings offer managerial and societal implications for cognitive interventions to develop customers’ SCL, which is aligned to customers’ needed literacy for co-creation and well-being.

The newly proposed concept of SCL is shown to be more appropriate in research adopting the service-dominant logic. Its importance as one type of customer operant resource for value co-creation is underscored. Findings also uncover how other actors indirectly contribute to customers’ value co-creation via developing their SCL resources.

Drawing on scholarships of workplace romance, LGBT at work and sexual fluidity, this present research aims to investigate the effect of female sexually fluid romantic relationships at work on their work and life.

The authors used qualitative approach and interviewed 30 female workers who experienced sexual fluidity at work.

From interviews with 30 female employees in Vietnam who experience fluidity in their romance, the authors find out positive and negatives effects on their psychology at work (affective/behavioral/cognitive change and mental health), work outcome (job attitudes and performance/productivity) and relations with coworkers.

This research discovers common and distinct features in the workplace romance of female sexually fluid employees. The research finding supports queer perspective which is exerting more salient impacts on our contemporary society and workplace.

Official development assistance (ODA) education projects have played a crucial role in improving education and training fields in developing countries, but are often facing several considerable challenges (e.g. long implementation time). Thus, this study aims to identify critical success factors (CSFs) in ODA education projects and investigate the influences of CSFs on ODA project performance measured by 11 nonprofit outcomes (NPOs).

A comprehensive literature review and expert interviews were conducted to compile a list of 35 potential success factors for ODA education projects. Using a survey questionnaire, 143 valid responses were collected from practitioners joining ODA projects in Vietnam. Various statistical methods (e.g. mean score method, Spearman rank correlation test, analysis of variance test, factor analysis and regression analysis) were used to analyze the collected data.

This research identified seven CSFs for ODA education projects in Vietnam: comprehensive project management competency (C1), clarity and compliance in project execution (C2), transparency and committed funding (C3), external context conditions (C4), well-controlled design and project management procedures (C5), preparations in equipment and complexity insight (C6) and punctual site delivery (C7). Furthermore, the results of regression analysis indicated that comprehensive project management competency (C1) and transparency and committed funding (C3) could significantly affect various NPOs.

This study offers significant insights for practitioners (e.g. project managers) to improve ODA projects’ performance and effectiveness in the education and training sector of a developing country context (like Vietnam).

One Commune One Product (OCOP) program, a rural economic development program in Vietnam, aims to empower local communities for sustainable social and economic welfare development, protect the environment and preserve tradition. This study aims to employ this program associated with tourism to support small family businesses in rural areas cost-effectively.

This study used the geographic location mapping method to design tourist routes that connect tourism resources with OCOP producers. A stakeholder approach was employed to identify suggested practical works that need to be implemented while developing this tourism initiative.

Four rural districts of Bac Giang Province, a northern province in Vietnam known as the place of various indigenous people live and traditional craft villages. Many cultural and historical tourist sites have been chosen as sample areas for this study. By using Google map, based on the Bac Giang Tourist Map and a list of recognized OCOP products in Bac Giang Province, main tourist sites (16 locations) and small family businesses (known as cooperatives and households) that have OCOP products (17 places) in the four districts have been identified. Four notable tourist routes have been formed to propose four thematic tours (two 1-day tours and two 2 days-1 night homestay tours). Suggestions for related stakeholders to ensure the sustainability of this initiative are provided.

This study is supposed to be a model of promoting small family businesses through OCOP programs and tourism activities in a sustainable way in Vietnam. The outcome of this study is in line with the stakeholder theory emphasizing the systematic connection of various stakeholders such as employees, suppliers, local communities, government agencies and others towards complex business sustainability. The results of the study cannot conclude the small family businesses in Vietnam because it adopts geographic location mapping alone. Moreover, this study focused on OCOP programs only. Future research can use other methods of primary data collection, especially from tourists' perspectives. Data triangulation can be done to explore and verify the tourist routes that have been formed according to the four thematic tours proposed. Future research could also compare hotels managed by family businesses with non-family businesses.

This study is supposed to be a model of promoting small family businesses through OCOP programs and tourism activities in a sustainable way in Vietnam.

This study aims to address two relatively unexplored issues in banking service literature. The first relates to the impact of co-creation behaviors of frontline employees (FLEs) on their well-being. The second is the impact of FLEs' adaptability on their performance of co-creation behaviors and their well-being in the workplace.

A structural model was built and tested using survey data collected from 366 FLEs offering financial consulting services to customers at banks.

FLE co-creation behaviors have positive impacts on FLEs’ well-being, including well-being in the workplace (job satisfaction) and general well-being (quality of life). Moreover, FLEs with a high level of interpersonal and service-offering adaptability perform co-creation behaviors better than those with lower adaptability and have higher job satisfaction. Between service-offering adaptability and interpersonal adaptability, the former has stronger effects than the latter.

The findings suggest that banks develop and enhance FLEs’ adaptability and co-creation behaviors to enhance their well-being and customer value.

Prior research on FLEs' co-creation mainly focuses on customer-related transformative outcomes, leaving their own well-being less examined. This study fills this gap by providing evidence to suggest that although active co-creation behaviors require FLEs to have more skills and put in more effort, they do bring about transformative impacts in terms of better job satisfaction and quality of life. Additionally, a high level of adaptability helps FLEs to comfortably perform their co-creation behavior, thereby reducing stress and improving well-being.
